Recent Advances in Graphitic Carbon Nitride-Based Chemiluminescence, Cataluminescence and Electrochemiluminescence

Abstract

Graphitic carbon nitride (g-C 3 N 4 ) has attracted considerable attention due to its special structure and properties, such as its good chemical and thermal stability under ambient conditions, low cost and non-toxicity, and facile synthesis. Recently, g-C 3 N 4 -based sensors have been demonstrated to be of high interests in the areas of sensing due to the unique optical, electronic and catalytic properties of g-C 3 N 4 . This review focuses on the most salient advances in luminescent sensors based on g-C 3 N 4 , chemiluminescence, cataluminescence and electrochemiluminescence methods are discussed. This review provides valuable information for researchers of related areas and thus may inspire the development of more practical and effective approaches for designing two-dimensional (2D) nanomaterial-assisted luminescent sensors.

Modified carbon nitride nanozyme as bifunctional glucose oxidase-peroxidase for metal-free bioinspired cascade photocatalysis

“…In addition, chemical functional groups and electronic properties of the GCN can be easily varied through simple modification 25–27 , which makes it a promising photocatalyst for H 2 O 2 production. Although GCN with good biocompatibility has been also employed as a peroxidase-mimicking nanozyme for glucose detection 28–30 (Supplementary Table 1), its GOx-mimicking behaviour has never been explored in enzymatic tandem cascade (domino) reactions for colorimetric detection of glucose.…”

Nanozyme‐based luminescence detection

“…Some nanomaterials possess the properties of luminescence and cataluminescence. [ 113 ] Therefore, it might be possible to develop low cost and high stability nanomaterials as substrates of nanozymes.…”

Advances in Electrochemical Aptasensors Based on Carbon Nanomaterials

“…The defects of the MWCNTs walls are decorated with oxygen-containing functional groups involved in redox catalysis of the electron transfer [73,74]. (5,5) Armchair (9,0) Zigzag Graphitic carbon nitride g-C3N4 (Figure 3) is obtained by the polymerization of nitrogen rich precursors (cyanamide, urea, thiourea, melamine) performed by physical vapor deposition, CVD, solvothermal method or solid-state reaction [75]. The above reactions result in the formation of a non-volatile product, which can be transferred into the various nano-and microstructures, including nano flacks and microrods by exfoliation conducted under partial oxidation, sonication or chemical treatment.…”
